This code allows for platform-specific ways to allocate and free TransportDIBs. This is needed by the BrowserPlugin. Make them public so that they can be accessed by the BrowserPlugin BUG=none Review URL: https://chromiumcodereview.appspot.com/10826100 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@149538 0039d316-1c4b-4281-b951-d872f2087c98
